The AirTAC GFR400C15LC2W AirTAC Filter Regulator PT1/2, 5 um is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has See datasheet ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The GFR400C15LC2W is an AirTAC GFR400 filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This configuration is built on a 1/2 in PT port, carries the finer 5 um filter element (code W), uses a differential-pressure drain, and is the low-pressure (L) type for circuits regulated below the standard range. A round external gauge with a psi scale is fitted, and the mounting bracket is included.
It is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, PT, G (BSPP) or NPT threads, manual, automatic or differential-pressure drains, 40 um standard or 5 um filtration, and gauge choices; the 400 size bowl is polycarbonate. Max inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm sizing and the low-pressure adjustment range against your application.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

On a finishing line, this unit filters the shop air to 5 um and holds a low regulated supply to the spray guns, keeping moisture and particles out of the finish.
Feeding pilot-air manifolds on an automated machine, the 5 um element protects directional-control valves from water and debris while the regulator holds a steady low pilot pressure.
On a low-pressure clamping or forming fixture, the unit regulates cylinder force gently and the psi gauge gives the operator a direct, readable setpoint.
Size 400 with a 1/2 in PT port suits lines plumbed at 1/2 in; step up to 600 or down to 300 depending on the flow your circuit needs - we can check the published flow curves against your demand before you order. The 5 um element (W) is the finer of the two published grades (40 um is standard); choose it where downstream valves or instruments need cleaner air. The differential-pressure drain flushes the bowl automatically as pressure drops across the element; manual (M) and automatic (A) drains are order options. This is the low-pressure (L) type, intended for circuits regulated below the standard range - confirm the exact adjustment range with us. The round external gauge is fitted with a psi scale; MPa and bar scales and an embedded square gauge are alternatives. Thread is PT as standard, with G (BSPP) and NPT available to order, and the bracket is included.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for this family as curves, not a single rated figure, so we do not quote a number. Tell us your application and line pressure and we will confirm the flow from the datasheet on request.
It marks the low-pressure type of regulator, intended for circuits held below the standard adjustment range. The exact range for this variant is not published on our catalogue sheet, so we confirm it on request before you order.
